TRANSMISSIONGEARING.

Specification of Letters Patent.

Patented May 12, 1914.

To all whom it may concern Be it known that I, ADoLrH N. MILLriR,residing in Milwaukee, in the county of Mllwaukee and State ofWisconsin, have 1nvented new and useful Improvements inTransmission-Gearing, of which the following is a description, referencebeing had to the accompanying drawings, whlch are a part of thisspecification. y 0

My invention consists in certain peculiarities of construction andcombination of parts hereinafter set forth with reference to theaccompanying drawing and subsequently claimed, its object being toprovide simple, positive, and durable gearing, the arrangement andconstruction of which is such that motion in one direction from apower-shaft is quickly and positively transmitted to a counter-shaft ineither direction, the gearing being in constant mesh.

The drawing represents a sectional plan view of a transmission gearingembodying the features of my invention, the parts being shown inposition wherein the powershaft gearing is uncoupled from the counter.

Referring by numeral to the drawing, 1 indicates a frame, in bearings ofwhich is mounted a power-shaft 2, the shaft being provided withoppositely disposed conical clutch members 3' that are secured to saidshaft. Beveled pinions 4 are loosely mount-l ed upon the shaft havingcollared sleeve exy tensions 5, which extensions are held againstend-thrust by bearings of the frame'located between the beveled pinionsand collared ends of their respective sleeves. Each bevel pinion isprovided with a rearwardly extending conical shell 6 into which arehoused the clutch members 3, said clutch-members being arranged to bealternately forced into frictional engagement with the shells.Engagement of the clutchmembers and shells is accomplished by means of alever 7 fulcrumed to the frame 1 and in Spanner-engagement with agrooved collar 8 fast on the power-shaft 2. By this construction it isapparent that when the power-shaft is moved longitudinally in eitherdirection by the lever, from the position shown in the drawing, one orthe other of the beveled pinion shells will be engaged by the adjacentclutch-member whereby a rotation of said pinions is effected. Meshingwith both beveled pinions 4 is a beveled gear-wheel 9, which gearwheelis secured to a countershaft 10, this shaft being mounted in bearings ofthe frame and carrying a toothed sprocket-Wheel 11 for transmittingmotion by a chain (not shown) to a vehicle-axle or any mechanism desiredto be actuated.

From the foregoing described gearing, it is obvious that the power-shaftdriven in one direction, will cause the counter-shaft to rotate ineither direction at the will of the operator, or said counter-shaft maybe disconnected from the power-shaft entirely, depending upon theposition of the clutchmembers, and when either pinion is operating todrive the aforesaid counter-shaft, the opposite4 pinion is idly rotatedin a reverse direction by the gear-wheel, thus serving as acounter-balance.

It should be understood that in some instances, for the toothed beveledpinions and gear-wheel, friction-gears may be substituted, but in eitherinstance the reversing mechanism is the same, which mechanism comprisesthe conical clutch members and their-conical shells or housing carriedby the beveled pinions.

The conical shells 6 are providedv with flanged portions 12 to which areconnected extension portions 13 provided with hubs 14. These hubportions surround the shaft and have bearings 15 in the main frame 1.The shaft openings in the hub portions are of larger diameter than theshaft 2 -which passes freely 'therethrough and has its bearings intheframe beyond the bearings of the hub. By providing the conical shellswith the extension portions the weight of the shells is carried bybearings on both ends of each shell thereby greatly increasing the wearand life of the parts.

lVhat l claim as my invention is:

1. A transmission device, comprising a longitudinally movable powershaft, clutch members `fixed thereon, oppositely positioned drivingwheels surrounding the shaft and each driving wheel having a bearingupon the inner side of and upon the outer side of each clutch member,said driving wheels also provided with clutch portions positioned to beengaged by the clutch members fixed on the power shaft, a driven shaftand a driven wheel carried thereby in mesh with both driving wheels, andmeans for imparting .longitudinal movement to the power shaft to moveone or the other of the clutch members into engagement with one or theother clutch portions of the drivin ywheels to alternately change thedirection o rotation of the driven shaft.

2. A transmission device, comprising a longitudinally movable powershaft, clutch members fixed thereon, oppositely positioned .drivingwheel-s loosely surrounding the shaft, the loosely surrounding portionsof the driving wheels forming inner bearings for said wheels upon theshaft, outer bearings for the driving wheels rigidly fixed to saiddriving wheels so as to be non-movable longitudinally therewith, adrivenshaft, and a driven wheel carried thereby in mesh with the driv- Iing wheels, and means for imparting longitudinal movement to the powershaft to move one or the other of the Xed clutch members into engagementwith one or the other clutch members of the driving wheels toalternately change the direction of rotation of the driven shaft. v

l 3. A transmission device, comprising a longitudinally movable powershaft, clutch members fixed thereon, oppositely positioned drivingwheels loosely surrounding the shaft, the loosely surrounding portionsof the drivouter bearing consist-ing of a portion loosely l surroundingthe shaft, and a projection extending inwardly from said looselysurrounding portion and xedly secured to the outwardly extending clutchmember of the driving wheel adjacent thereto, a drivenl shaft, and adriven wheel carried thereby in mesh with the driving wheels, and meansfor imparting longitudinal movement to the power shaft to move one orthe other of the fixed clutch members into engagement with one or theother clutch members of the driving wheels to alternately change thedirection of rotation of the driven shaft.

In testimony whereof, I aiix my signature, in presence of two witnesses.
